C. and at most 270.degree. C., thereby leaving a residual coal-based heavy oil, the residual coal-based heavy oil is mixed with a ketone-type solvent having a boiling point less than 200.degree. C. to form an insoluble precipitate (including quinoline insolubles) and a supernatent, the supernatent is treated to recover the ketone-type solvent, and the remaining hydrocarbon mixture is easily processed by vacuum distillation to produce a hydrocarbon product suitable for making carbon stocks.

摘要： A molding process of a molding compound containing an ingredient such as a binder, e.g., pitch or a thermosetting resin which generate gas before being set, is disclosed, wherein the molding compound is heated and molded under pressure according to a special temperature pattern. First, the molding compound may be preheated substantially uniformly to a temperature at which the binder melts and generates reaction gas. Next, temperature gradient in the direction of thickness of the molding is created while raising the temperature of the molding to an upper limit temperature so that the setting of the molding progressively advances from the higher temperature to the lower temperature side of the molding.
